Flying Squirrel Facts & Information

Depending on the species, flying squirrels range in color from white to gray to brown with a pale belly. They should be called “gliding squirrels” because they aren’t capable of true powered flight like birds or bats. They have a special membrane between their front and back legs that allows them to glide through the air between trees. They stretch out their legs, spreading the fold of skin between the front and hind legs, to form a kind of parachute that lets them glide from branch to branch. While gliding, they are very agile and can turn and change their angle of decent. They land very lightly on all four feet. In contrast, however, flying squirrels are relatively clumsy on the ground. Adult flying squirrels are relatively small, as their head, body, and tail length totals around 10 inches. On average, they weigh anywhere from 2 to 6 ounces. Flying squirrels have large black eyes and 22 teeth.

For the southern flying squirrel, there are usually two litters each year with the young born between April-May and August-September. The gestation period is about 40 days, and they have roughly 2-6 young per litter. Alternatively, the northern flying squirrel has only one litter each year, with roughly 2-5 young born in May-June. Occasionally, there is a second litter in the autumn.

Flying squirrels become pests only when they take up residence in an attic where they can cause odor and damage with their urine, and keep people awake with their nocturnal activity. Medically speaking, however, flying squirrels are of little concern. While these squirrels have been implicated in the spread of human diseases, direct transmission is rare. Amazing to see, but not great to see in your home or business.
